Court leaves in place rule for ads on airfares

The Supreme Court is refusing to review a federal rule that requires airlines to include taxes in their advertised fares, a practice that carriers say violates their free-speech rights.

Under a Transportation Department rule that was upheld by a federal appeals court, airlines must display the total cost of a ticket in the largest type size and have it be the most prominent price in ads or on their web pages. Airlines still can break down the price of a ticket to show taxes and fees.
